Abstract
A display device and a manufacturing method of a display device are provided. A display device includes a base substrate; an electrode on the base substrate, a light emitting element on the base substrate and electrically connected to the electrode, and a solution layer between the base substrate and the light emitting element, the solution layer including a light blocking material.
Claims20
A display device comprising:
- a base substrate;
- an electrode on the base substrate;
- a light emitting element on the base substrate and electrically connected to the electrode, the light emitting element comprising a main body part and a contact part, the contact part being in contact with the electrode so as to be electrically connected to the electrode;
- and
- a solution layer between the base substrate and the light emitting element and in direct contact with the contact part,
- wherein the solution layer comprises a solvent and a light blocking material dispersed or decomposed in the solvent.
